It's a vehicle tax. It's depending on emissions at the moment as a way to encourage vehicles with low/no emissions but there is no reason for EV to keep being exempt. The issue in term of tax revenue is fuel duty and VAT on fuel. I'm suspecting that once transition is advanced enough they'll find ways to add tax on charging points/electricity used for charging, or an actual road tax on mileage or whatnot.
